msgid "It is now time to configure ALSA to use the @emph{bluealsa} Bluetooth module, so that you can define an ALSA pcm device corresponding to your Bluetooth speaker.  For a headless server using @emph{bluealsa} with a fixed Bluetooth device is likely simpler than configuring Pulseaudio and its stream switching behavior.  We configure ALSA by crafting a custom @code{alsa-configuration} for the @code{alsa-service-type}.  The configuration will declare a @code{pcm} type @code{bluealsa} from the @code{bluealsa} module provided by the @code{bluez-alsa} package, and then define a @code{pcm} device of that type for your Bluetooth speaker."
msgstr "Teraz je čas nastaviť ALSA na používanie Bluetooth modulu @emph{bluealsa}, aby ste mohli určiť ALSA pcm zariadenie zodpovedajúce vášmu Bluetooth reproduktoru.  Pre bezobrazovkový server je použitie @emph{bluealsa} s pevne určeným Bluetooth zariadením pravdepodobne jednoduchšie ako nastavenie Pulseaudia a prepínania tokov.  ALSA nastavíme vytvorením vlastného nastavenia @code{alsa-configuration} pre druh @code{alsa-service-type}.  Nastavenie zadá @code{bluealsa} @code{pcm} druhu z modulu @code{bluealsa} poskytovaného balíkom @code{bluez-alsa} a potom určí @code{pcm} zariadenie daného druhu pre váš Bluetooth reproduktor."

Even when using Guix on a foreign distribution you can benefit from the design of Guix System by running a system instance as a container.  Using the same kernel features of unshared namespaces mentioned in the previous section, the resulting Guix System instance is isolated from the host system and only shares file system locations that you explicitly declare."

While in a container shell the containerized process is a Bash shell process, a Guix System container runs the Shepherd as PID 1.  In a system container all system services (@pxref{Services,,, guix, GNU Guix Reference Manual}) are set up just as they would be on a Guix System in a virtual machine or on bare metal---this includes daemons managed by the GNU@tie{}Shepherd (@pxref{Shepherd Services,,, guix, GNU Guix Reference Manual}) as well as other kinds of extensions to the operating system (@pxref{Service Composition,,, guix, GNU Guix Reference Manual})."

msgstr "Pozorovanú zvýšenú zložitosť v používaní kontajnerov so systémom Guix možno jednoducho zdôvodniť keď sa musíte vysporiadať so zložitými aplikáciami, ktoré majú vyššie či len prísnejšie požiadavky na prostredie, v ktorom sú spúšťané, napr. súbory nastavení, vyhradené používateľské účty, priečinky vyrovnávacej pamäte, súbory záznamov a pod.
